With these and other objects in view, the ,invention consists in certain details of? construc: tion and combinations and arrangements of" parts, all -aS';Wi1'il.1Hl=eiL1tfiE-Zbfeedrmfesfully described, and the novel features thereof panticue larly pointed out in the apnefidedwclaimse. .i

Fig. 2 is a similar view showing a modified form of the invention.

The body of the aeroplane is indicated at and journaled in the body and extending longitudinally thereof is a spindle I I which constitutes the propeller shaft on which the propeller blades I! are mounted. The body III, with associated structural parts such as the wings, rudder and the like may, of course, be of any desired style, design, or configuration.

In the form of the invention illustrated in Fig. 1 the propeller shaft II is adapted to be rotated alternately in opposite directions by lengths of cord A and B which are adapted to be wound on the spindle H in opposite directions. The free end of cord B is anchored to the crossbar I9 of a supporting structure. Crossbar l9 may be located at any desired height, depending upon the length of the standards (not shown) on which it t m,thecopp sitadirectmn.b

In the modified form of'the invention mus: trated in Fig. 2 the body ll! of the toy is attached to the lower end of a. suspension cord or cable l3 by which the plane can be raised and lowered, the cord I3 being adapted to run through an eye l8 in the cross member l9 in the sam fashion as cord A is operated in the previously described form of the invention. Attached to the shaft II are two impeller cords or cables l4, l6, which are adapted'to be wound in opposite directions on shaft l I with their free ends extending through suitable openings in the bottom of the plane. Cord I4 is of a length double that of cord l6 and attached to the free end of cord I6 is a weight I! so that by anchoring the free end of cord l4 and raising the plane upwardly from the point of anchorage, cord M will unwind and turn shaft II with the result that the reversely disposed cord It will be wound up on the shaft. Similarly, after cord l6 has thus been wound on the shaft, if the plane is then lowered, weight I! causes the shaft l I to turn in a reverse direction and wind cord H on the shaft.

For instance, as shown in Fig. 2, when the Plane is in its lowered position with cord l4 wound on shaft H and with the free end of that cord anchored to the ground or other surface as by a weight l5 heavier than weight l1, an upward movement of the plane will cause the shaft ll to turn by reason of weight l5 being heavier than weight H with the result that cord 16 will be wound on the shaft in a direction opposite to the windings of cord M. This shaft, together with blades l2 will continue to rotate until the plane is raised the full length of cord [4. After the plane has reached its uppermost limit of movement, it is then lowered and as cord I4 is thus slackened it is rewound on the shaft by the action of weight I! which causes the cord IE to unwind. Thus shaft H and blades l2 are revolved in the opposite direction until the weight ll comes to rest on the ground or other surface, this being the lower position of the plane as illustrated in Fig. 1.

As will be appreciated, 2. child playing with the toy can raise and lower the plane repeatedly and in this way cause the propeller blades to revolve substantially continuously, although alternately in opposite directions to simulate a plane in flight. By using a weight on the longer cord [4 heavier than the weight on cord M5 for anchoring the otherwise free end of the longer cord, the toy can be operated in the house as well as out of the house. For instance, as indicated, with the elevating cord A or l3 free to run through an eye fastened in the crossbar l9 of the supporting structure located the proper distance above the floor or ground surface the crossbar can be located a considerable distance above the ground, much higher than a child could reach, and the plane raised and lowered by the child holding the free, depending end of the operating cord l3. In this way, the plane is capable of what might be considered by the child rather extended flights, all of which will increase the app al of the toy to young children.

What I claim is:

1. In a toy aeroplane comprising a body and a propeller shaft journaled therein, a driving cord having one end attached to said shaft and wound on said shaft, a second driving cord having one end attached to said shaft and wound in the reverse direction on said shaft, weights attached to the free ends of said cords extending outwardly and downwardly from the body, one of said cords being of greater length than the other and the weight attached to the longer cord being adapted to rest on a base and being heavier than the weight attached to the shorter cord, both of said cords being movable relative to the body, and means for raising and lowering said body.

2. In a toy aeroplane comprising a, body and a propeller shaft journaled therein, a cord attached at one end to said shaft adapted to be wound on said shaft by rotary motion of the shaft in one direction, a weight attached to the other free end of said cord, a second cord having one free end and its other end attached to said shaft and adapted to be wound on th shaft by reverse rotation of said shaft, said second cord bein double the length of the first cord, 2. second heavier weight attached to said second, longer cord adapted to rest on a base, said cords bein movable relative to said body and extending outwardly and downwardl therefrom whereby when the plane body is raisedfabove the heavier weight the full length of the cord attached to said heavier weight the shorter cord will be fully wound on said spindle and when the plane is lowered from said raised position the weight on the shorter cord will unwind the latter and wind the longer cord on said shaft.

3. In a toy aeroplane apparatus comprising an aeroplane body having a propeller shaft journaled therein, a supporting structure, means for suspending said body from said support and alternately raising and lowering the body relative to said support, a cord wound on said shaft and having one end attached to said shaft, a weight suspended from the other end of said cord below said body, and a second, longer cord wound in the opposite direction on said shaft and having one end attached to said shaft and its other end anchored below said body, whereby when the body is raised on its support the anchored cord will wind the weighted cord on the shaft and when said body is lowered from its raised position the weighted cord will wind the anchored cord on said shaft.
